Wehrli 04.5-07 Dodge Ram Cummins 4in Down Pipe - w/High Mount S400 Turbo & 2nd Gen Manifold

The 4.6-inch diameter upper flange on this Wehrli down pipe is specifically sized to connect with the exhaust housing of an S400 turbocharger. This Wehrli Custom Fab down pipe is built for your 2004.5-2007 Dodge Ram 5.9L Cummins, especially when you're running a high-mount turbo setup with a 2nd Gen style exhaust manifold. It's designed to bolt directly to the V-band flange on your factory exhaust system, meaning you won't need to cut or modify your existing exhaust to install it.

This down pipe is finished with a high-temperature ceramic coating to help manage heat, and it comes with heat wrap and clamps for added protection. The lower flange uses the factory V-band clamp connection, making for a straightforward installation. This version is specifically for the S400 turbo with a flat exhaust housing flange, ensuring a proper seal and connection.

While this down pipe is designed for a direct fit on the 2004.5-2007 models, it can also be used on 2003-2004 trucks if the front exhaust pipe has been updated to the later style. A new OEM V-band clamp for the lower connection is sold separately, so be sure to grab one if yours is worn out.
